converting a rainier to an NRS?

[mr_dove]

My wife currently has a giant rainier, but has expressed some interest in having a full suspension rig.

My idea is to purchase an NRS frame and build it up with all the parts from the Rainier. Can anyone tell me if I would run into any component compatibility problems between the two frames. i.e. Are there any Rainier parts that won't work on the NRS frame?

As long as all the parts would transfer over, it would be great.

Everythingon the rainier wouod fit on an NRS, I think:D

generally speaking, when building up a new frame with old parts, you will run into issues at:

-steerer tube length
-headset size (shouldn't be a prob for you). stem & fork type can change with headset size...
-bb spindle and shell width
-seatpost diameter
-seat binder diameter
-tire clearance (shouldn't be a prob)
-front deraileur clamp diameter

The reason that Giant is able to keep costs low is because they buy in MASSIVE quantities, they buy build kits from shimano in bulk like bike shops buy tubes in bulk from manufactorers.

That means that the BB should be the same width and threading. the NRS has plenty O' tire clearance so that Isn't a prob, but be dude and pick some new ones up.

also, the NRS frames still have a problem with rear derailliers hitting the frame when riding in the rough and during drops. the remady is that you take some old tires or grips and zip tie them to the frame where the Deraillier contact, or zip tie them directly to the deraillier. you probably wont be able to do both because it might cause ghost shiffting while your in smaller gears because the deraillier movement will be limited via the bumpers

Actually, this is only true with pre-2002 models. For 2002 we re-designed the seatstays by the dropout, giving the der. the 90 or so degrees of clearance that Shimano requires. All bikes with a Horst link will have clearance issues, unless they have been designed to accomodate the der.
SRAM der. will not contact, because they do not pivot at the bolt like the Shimanos.

Hope this helps...

Yes, my origianal assumption was that all the parts would be of the same size and dimensions because it's just cheaper to work that way.

since james didn't say otherwise, I'm going to assume that all parts will in fact work on the NRS frame.

thanks

thanks Whoops, sorry. Yes, everything should just swap over, including the internal headset. The one thing I'm not sure of is the seatpost. If it's a 27.2mm, you're set, but I cannot remember which size is in the Rainier.
Good luck.

What type of brakes does your Rainer have? Some models of the NRS do not have V-brake mounts on the frame and are disk only? Just be sure what ever frame you buy have V-brake mounts if that's what your Rainer has.

I believe the last couple of years Giant has made the rainier a disk only bike.
I got dibs on the frame if you are gonna sell it :rolleyes:

I have done it twice here at my shop. They both use a 27.2 post with a shim, so that was not a problem. The Avid brakes work fine on the NRS. Though you will need a few longer bits of housing to fit the seatpost,seat stay area. It should make your wife a fine XC bike!
